Description

Technical Field

[0001] The present invention relates to a massage ball, and more particularly to a massage ball with improved heat transfer performance. Background Art

[0002] In the past, in order to relieve acute or chronic pain in the muscles and nerve tissues of the spine caused by working in an improper posture for a long time or getting used to such a posture, improve blood circulation in the body, or eliminate instantaneous muscle soreness, spinal thermal massage devices have been widely used. While moving along the body parts, they apply thermal stimulation to the painful parts to improve blood flow.

[0003] The spinal warming massage device has a massage ball that can generate heat so that the user can be warmed while being pressed. A PTC heater that can be heated by applying an electric current is provided at the center of the massage ball.

[0004] However, the PTC heater is fixed in a non-rotating state at the center of the massage ball in order to connect to a power source. If constructed in this way, there is a problem that a slight gap is formed between the PTC heater fixed in a non-rotating state and the rotatably arranged massage ball in order to allow relative rotation, thereby reducing the warm massage effect.

[0005] At this time, the PTC heater and the massage ball may be configured in contact with each other to transfer heat by conduction. However, if configured in this way, noise may be generated due to friction during the rotation of the massage ball, and wear may occur therebetween, resulting in a problem of reduced durability.

[0006] Therefore, there is a need to develop a technology that can solve this problem. Summary of the invention

[0066] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings so that a person having ordinary knowledge in the technical field to which the present invention belongs can easily implement the present invention. However, the present invention can be implemented in various forms and is not limited to the embodiments described herein. In order to clearly illustrate the present invention, parts not related to the description are omitted in the accompanying drawings, and the same reference numerals are given to the same or similar components throughout the specification.

[0067] The words and terms used in this specification and claims shall not be interpreted limited to their usual or dictionary meanings, but shall be interpreted in accordance with the principle that the inventor can define terms and concepts in order to best explain his invention so as to conform to the meaning and concept of the technical idea of ​​the present invention.

[0068] Therefore, the embodiments described in this specification and the structures shown in the drawings belong to a preferred embodiment of the present invention and do not represent all technical ideas of the present invention. Therefore, the structure may have various equivalents and modifications that can replace it at the time of application of the present invention.

[0069] In this specification, terms such as "including" or "having" should be understood as specifying the existence of features, numbers, steps, actions, components, parts or combinations of these recorded in the specification, and do not exclude in advance the possibility of the existence or increase of one or more other features or numbers, steps, actions, components, parts or combinations of these.

[0070] Figure 1 is a perspective view showing an assembled state of a massage ball with improved heat transfer performance according to an embodiment of the present invention; Figure 2 The present invention is a perspective view showing a massage ball with an improved heat transfer performance with its outer cover removed. Here, direction a refers to the axial direction, direction b refers to the radial direction, and direction c refers to the circumferential direction.

[0071] like Figure 1 and Figure 2 As shown, a massage ball 100 with improved heat transfer performance according to an embodiment of the present invention is a massage ball 100 that provides a warm massage effect while pressurizing a user, and the massage ball 100 also includes: a heating component 120; a rotating component 130, which is rotatably inserted and configured in the heating component 120; and an external cover 140, which is rotatably configured outside the rotating component 130.

[0072] That is, since there is a rotating part 130 rotatably inserted into the heating part 120 and an external cover 140 rotatably arranged outside the rotating part 130, the heat transfer is conducted by the rotating part 130, which can improve the warm massage effect. Moreover, the rotating part 130 can make the external cover 140 rotate smoothly, so that no noise is generated during use, and there is no problem of reduced durability due to wear. Such an external cover 140 can be made of an elastic material to reduce the pain caused by the pressure when the massage ball 100 presses the user during the warm massage. For example, the external cover 140 can be made of a silicon material.

[0073] At this time, the massage ball 100 may include at least one of the first side panel 110 and the second side panel 150, wherein the first side panel 110 is arranged on one side of the axial direction a, and the second side panel 150 is arranged on the other side of the axial direction a. At this time, the first side panel 110 can be fixed and combined with the support arm 21. This support arm 21 is arranged on the support part 20 of the warm massage device to be described later, and can be configured to rotate at a predetermined angle during the warm massage process. The first side panel 110 is fixed and combined with the support arm 21, and the heating component 120 is fixed and combined with the first side panel 110, so that the massage ball 100 can stably support the body of the user during the process of pressurizing the user, and not only that, the heating component 120 can be stably supplied with current.

[0074] That is, when the support arm 21 is fixed and combines the first side plate 110 and the heat generating component 120 , the rotating component 130 is rotatably inserted into the heat generating component 120 , and the outer cover 140 is rotatably disposed outside the rotating component 130 .

[0075] Figure 3 is a perspective view showing a heat generating component according to an embodiment of the present invention; Figure 4 1 is a front view showing a heat generating component according to an embodiment of the present invention.

[0076] like Figure 3 and Figure 4 As shown, the heat-generating component 120 may include a heater 121 and a heater cover 122 , wherein the heater cover 122 is configured to surround the heater 121 and has a heat transfer surface hs on the outside.

[0077] That is, when the heater 121 is supplied with current and generates heat, the heat is transferred through the heater cover 122 and then transferred to the rotating member 130 through the heat transfer surface hs. Heat is transferred by such conduction, thereby improving the warm massage effect. In this case, the heater 121 may be a PTC heater, but it is not limited to this. As long as it is a structure that can generate heat, it may also be other structures such as a hot wire.

[0078] The heater cover 122 may be fixed to the first side plate 110 .

[0079] like Figure 3 and Figure 4 As shown, the heater cover 122 includes a first cover 122a and a second cover 122b, wherein the first cover 122a is arranged on one side of the radial direction b, and the second cover 122b is arranged on the other side of the radial direction b and can be combined with the first cover 122a; wherein the heater 121 can be arranged between the first cover 122a and the second cover 122b.

[0080] That is, the first cover 122a and the second cover 122b can be combined, and the heater 121 and the heater cover 122 can be easily combined, thereby improving manufacturability. In this case, the first cover 122a can be configured to have a combination protrusion protruding toward the second cover 122b, and the second cover 122b can have a combination groove for inserting the combination protrusion, and the combination protrusion and the combination groove are combined by interference fit. Alternatively, it can also be configured to have a combination protrusion on the second cover 122b and a combination groove on the first cover 122a, so that the combination protrusion and the combination groove are combined by interference fit.

[0081] like Figure 3 As shown, the rotating member 130 may include a rotating pin 131 , and the rotating pin 131 is inserted into the heater cover 122 along the axial direction a.

[0082] At this time, the rotation pin 131 inserted into the heater cover 122 may be configured to rotate relative to the heater cover 122. That is, by configuring the rotation pin 131 to rotate relative to the heater cover 122 while being inserted therein, the outer cover 140 may be rotated more smoothly.

[0083] In addition, during the rotation of the outer cover 140 , heat can be transferred by conduction through the rotating pin 131 , thereby also improving the thermal massage effect.

[0084] In this case, a sliding surface may be provided on the outer surface of the heater cover 122. When the massage ball 100 presses the user, even if the outer cover 140 is deformed and contacts the heater cover 122, the outer cover 140 can rotate smoothly as long as it has a sliding surface.

[0085] Figure 5 is a front view showing an enlarged view of a slot in which a heat generating component is arranged according to an embodiment of the present invention; Figure 6 This is an enlarged front view showing a state in which a rotating pin is inserted into a slot provided in a rotating member according to an embodiment of the present invention.

[0086] like Figure 5 and Figure 6 As shown, the heat generating component 120 has a slot 122 c into which the rotating component 130 is inserted, and an outer opening 122 d may be provided outside the slot 122 c in the radial direction b to expose a portion of the rotating component 130 in the radial direction b.

[0087] That is, the rotating pin 131 may be exposed to the outside in the radial direction b from the slot 122 c through the outer opening 122 d , and the portion exposed to the outside in the radial direction b may be in contact with the outer cover 140 and heat may be transferred by conduction.

[0088] At this time, as described above, the outer surface of the heater cover 122 may also have a sliding surface, thereby allowing the outer cover 140 to smoothly rotate through the sliding surface even if the outer cover 140 is deformed and coupled to the heater cover 122 during the massage ball 100 pressurizing the user.

[0089] like Figure 5 and Figure 6 As shown, the rotating member 130 may have an exposed contact portion 131 a , and the exposed contact portion 131 a is exposed to the outside in the radial direction b through the outer opening portion 122 d .

[0090] That is, the exposed contact portion 131 a exposed to the outside in the radial direction b contacts the external cover 140 while transferring heat in a conductive manner.

[0091] At this time, as described above, the outer surface of the heater cover 122 may also have a sliding surface, thereby even if the outer cover 140 is deformed and contacts the heater cover 122 during the process of the massage ball 100 pressing the user, the outer cover 140 can smoothly rotate through the sliding surface.

[0092] Figures 7 to 10 is a perspective view showing a rotation pin according to various embodiments of the present invention.

[0093] At this time, the slot 122c may include at least one of a first slot and a second slot, wherein the first slot extends from one side to the other side of the axial direction a, and the second slot extends from the other side to one side of the axial direction a.

[0094] For example, Figure 7 As shown, the slot 122c may include a first slot extending from one side of the axial direction a to the other side. In this case, an anti-detachment surface may be provided on the other side of the axial direction a of the slot 122c to prevent the rotation pin 131 from detaching. With such a configuration, the staff can perform simple assembly by inserting the rotation pin 131 from one side of the axial direction a to the other side, thereby improving the assembly performance.

[0095] Take another example, Figure 8 As shown, the slot 122c may include a second slot extending from the other side of the axial direction a to one side. In this case, an anti-detachment surface may be provided on one side of the axial direction a of the slot 122c to prevent the rotation pin 131 from detaching. With such a configuration, the staff can simply assemble by inserting the rotation pin 131 from the other side of the axial direction a to one side, thereby improving the assemblability.

[0096] At this time, the narrow groove 122c includes a first narrow groove and a second narrow groove, wherein the first narrow groove extends from one side to the other side of the axial direction a, and the second narrow groove extends from the other side to one side of the axial direction, and the first narrow groove and the second narrow groove are alternately arranged along the circumferential direction c or can be arranged along the axial direction a.

[0097] For example, Fig. 9 As shown, the slot 122c includes a first slot and a second slot, wherein the first slot extends from one side of the axial direction a to the other side, and the second slot extends from the other side of the axial direction a to one side, and the first slot and the second slot can be alternately arranged along the circumferential direction c. If so configured, one side of the axial direction a of the outer cover 140 is supported by the rotation pin 131 inserted in the first slot, and the other side of the axial direction a of the outer cover 140 is supported by the rotation pin 131 inserted in the second slot, so that the outer cover 140 can rotate smoothly.

[0098] Take another example, Fig.10As shown, the slot 122c includes a first slot and a second slot, wherein the first slot extends from one side of the axial direction a to the other side, and the second slot extends from the other side of the axial direction a to one side, and the first slot and the second slot can be arranged along the axial direction a. If so configured, one side of the axial direction a of the external cover 140 is supported by the rotation pin 131 inserted in the first slot, and the other side of the axial direction a of the external cover 140 is supported by the rotation pin 131 inserted in the second slot, so that the external cover 140 can rotate smoothly.

[0099] Fig.11 2 is a cross-sectional view of a massage ball with improved heat transfer performance according to an embodiment of the present invention.

[0100] like Fig.11 As shown, the massage ball 100 may further include a second side plate 150, which is disposed opposite to the first side plate 110. Thus, if the second side plate 150 is provided, the rotating component 130 and the outer cover 140 may be prevented from being separated in the axial direction a during the relative rotation with the heating component 120.

[0101] At this time, the second side plate 150 can be configured to be arranged inside the outer cover 140 in the radial direction b. If so, when the massage ball 100 presses the user, the foreign body sensation felt by the second side plate 150 can be minimized.

[0102] Fig.12 is a perspective view showing a massage ball (with a first insert) with improved heat transfer performance according to another embodiment of the present invention; Fig.13 2 is a cross-sectional view showing a massage ball (with a first insert) with improved heat transfer performance according to another embodiment of the present invention.

[0103] like Fig.12 and Fig.13 As shown, the heater cover 122 may have an opening hole 122e extending along the axial direction a. The heat generated by the heater 121 is transferred by conduction through the heater cover 122. However, if the heater cover 122 has the opening hole 122e, the heat transferred by conduction only transfers to the remaining portion where the opening hole 122e is not formed due to the formation of an air layer in the opening hole 122e. This is because heat flows in a direction with less resistance. With such a configuration, the outer cover 140 can be quickly heated by the rotating member 130.

[0104] At this time, if Fig.12 and Fig.13As shown, the inner surface of the outer cover 140 may have a first insert 141. The first insert 141 may be made of aluminum material with high thermal conductivity so that the heat transferred by the rotating member 130 can be smoothly transferred to the outer cover 140, but it is not limited to this. Any material with high thermal conductivity may be used. The first insert 141 may be configured as a whole with the outer cover 140 by insert injection molding during the process of injection molding the outer cover 140.

[0105] In addition, the first insert 141 can extend from one end of the axial direction a of the outer cover 140 to the other end to ensure structural stability while supporting the inner surface of the outer cover 140. Accordingly, the outer cover 140 can be easily assembled during the manufacturing process of the massage ball 100. Moreover, even if a load of the user is applied to the massage ball 100 during a warm massage, the load can be stably supported.

[0106] Meanwhile, the first inserting member 141 may have a sliding surface on its inner surface. If the sliding surface is configured in this way, the outer cover 140 may rotate smoothly.

[0107] At this time, the first insert 141 may have a first transfer protrusion 141a, which is formed to protrude outward in the radial direction b, and a plurality of such first transfer protrusions 141a may be arranged along the circumferential direction c of the first insert 141. Accordingly, the heat transferred to the first insert 141 can be smoothly transferred to the outer cover 140. For example, the first transfer protrusion 141a may be bent into a protruding shape, but it is not limited to this, and may be any shape as long as it is a shape that can transfer heat in a conductive manner.

[0108] In addition, the first insert 141 may have a first fixing protrusion 141 b protruding outward in the radial direction b. The first fixing protrusion 141 b may have a curved surface to prevent the first insert 141 from being easily separated from the outer cover 140, thereby improving structural stability.

[0109] The first transmission protrusion 141 a and the first fixing protrusion 141 b may be formed integrally when the first insert 141 is manufactured, but may also be configured in a manner that the first transmission protrusion 141 a and the first fixing protrusion 141 b are attached to the first insert 141 as separate parts.

[0110] Fig.14 1 is a cross-sectional view showing a massage ball (with a second insert) with improved heat transfer performance according to another embodiment of the present invention.

[0111] Such a second insert 142 may be disposed at the central portion of the axial direction a of the outer cover 140. That is, the central portion of the axial direction a of the outer cover 140 is formed thicker to provide a sufficient cushioning feeling to the user, but the thickness of such an outer cover 140 necessarily reduces the warmth feeling provided to the user. Therefore, if the second insert 142 is provided inside the outer cover 140, the heat transferred to the inner surface of the outer cover 140 can be smoothly transferred to the outside of the outer cover 140 through the second insert 142.

[0112] In addition, if the second inserting member 142 reaches a thermal saturation state, even if the heat supply through the heater 121 is interrupted for a predetermined time, the second inserting member 142 can continuously provide a warm feeling to the user.

[0113] At this time, based on the second insert 142, the first buffer layer 140a is provided inside the radial direction b of the outer cover 140, and the second buffer layer 140b may be provided outside the radial direction b. If the first buffer layer 140a and the second buffer layer 140b are configured in this way, the foreign body feeling felt by the user due to the second insert 142 can be minimized, thereby providing the user with a sufficient buffering feeling.

[0114] Fig.15 1 is a cross-sectional view showing a massage ball (including a first insert and a second insert) with improved heat transfer performance according to another embodiment of the present invention.

[0115] like Fig.15 As shown, a first inserting member 141 is provided on the inner surface of the outer cover 140, and a second inserting member 142 may be provided at the central portion of the axial direction a of the outer cover 140. The specific structures of the first inserting member 141 and the second inserting member 142 are the same as those described above.

[0116] However, the first inserting member 141 and the second inserting member 142 may be connected to each other in the radial direction b. Thus, if the first inserting member 141 and the second inserting member 142 are connected to each other in the radial direction b, the structural stability of the outer cover 140 is improved.

[0117] In addition, as described above, in a state where the first insert 141 and the second insert 142 are connected to each other in the radial direction b, the first buffer layer 140a is provided between the first insert 141 and the second insert 142, and the second buffer layer 140b may be provided outside the outer cover 140 in the radial direction b. If the first buffer layer 140a and the second buffer layer 140b are provided in this manner, the first insert 141 and the second insert 142 can minimize the foreign body sensation that can be felt by the user, thereby providing the user with a sufficient buffering feeling.

[0118] At this time, the first insert 141 may have a first transfer protrusion 141a formed to protrude outward in the radial direction b, and a plurality of such first transfer protrusions 141a may be arranged along the circumferential direction c of the first insert 141. Accordingly, the heat transferred to the first insert 141 can be smoothly transferred to the outer cover 140. For example, the first transfer protrusion 141a may be bent into a protruding shape, but it is not limited to this, and may be any shape as long as it can transfer heat in a conductive manner.

[0119] In addition, the second insert 142 may have a second fixing protrusion 142a protruding inward in the radial direction b. The second fixing protrusion 142a is connected to the first insert 141 to prevent the first insert 141 and the second insert 142 from being easily separated from the outer cover 140, thereby improving structural stability.

[0120] Such a first transfer protrusion 141a may be formed integrally with the first insert member 141 when manufacturing the first insert member 141, or may be formed by attaching a separate first transfer protrusion 141a to the first insert member 141. In addition, the second fixing protrusion 142a may be formed integrally with the second insert member 142 when manufacturing the second insert member 142, or may be formed by attaching a separate second fixing protrusion 142a to the second insert member 142.

[0121] Fig.16 is a cross-sectional view showing a massage ball with improved heat transfer performance (rotating components and heat generating components are alternately arranged on an outer cover) according to another embodiment of the present invention; Fig.17 This is a cross-sectional view showing a massage ball with improved heat transfer performance according to another embodiment of the present invention (the rotating component and the heat generating component are both arranged on the outer cover).

[0122] At this time, the rotating member 130 may be inserted between the heat generating member 120 and the external cover 140. Fig.16 As shown, the rotating member 130 may be alternately arranged on the heat generating member 120 and the outer cover 140 along the circumferential direction c. The rotating member 130 inserted and arranged on the heat generating member 120 faces the outer cover 140 and contacts the outer cover 140 while exposing a portion of the rotating member 130 to the outer side in the radial direction b, and the rotating member 130 inserted and arranged on the outer cover 140 faces the heat generating member 120 and contacts the heat generating member 120 while exposing a portion of the rotating member 130 to the inner side in the radial direction b. If so configured, the heat generated from the heat generating member 120 is transferred by conduction through the rotating member 130, thereby improving the warm massage effect, and the outer cover 140 can rotate smoothly.

[0123] Or, if Fig.17As shown, the rotating component 130 can be arranged on the outer cover 140 at the same time as the heating component 120. That is, a part of the rotating component 130 is inserted and arranged on the heating component 120, and the remaining part of the rotating component 130 is inserted and arranged on the outer cover 140. If it is so constructed, the heat generated from the heating component 120 is transferred by conduction through the rotating component 130, thereby improving the warm massage effect. At this time, a part of the rotating component 130 can be exposed between the heating component 120 and the outer cover 140. If it is so constructed, the outer cover 140 can rotate smoothly by arranging the heating component 120 and the outer cover 140 at a distance from each other.

[0124] Fig.18 This is a cross-sectional view showing a massage ball with improved heat transfer performance (the rotating member is disposed on the outer cover) according to another embodiment of the present invention.

[0125] like Fig.18 As shown, a massage ball 100 with improved heat transfer performance according to another embodiment of the present invention is a massage ball 100 that provides a warm massage effect while applying pressure to a user, and the massage ball 100 includes: a heat generating component 120; an external cover 140 that is rotatably arranged outside the heat generating component 120; and a rotating component 130 that is rotatably inserted and arranged in the external cover 140. That is, the rotating component 130 inserted and arranged in the external cover 140 is facing the heat generating component 120 and is in contact with the heat generating component 120 while exposing a portion of the rotating component 130 on the inner side in the radial direction b. If so configured, the heat generated from the heat generating component 120 is transferred by conduction through the rotating component 130, so that the warm massage effect can be improved, and the external cover 140 can be smoothly rotated.

[0126] like Fig.18 As shown, the heat generating component 120 may include a heater 121 and a heater cover 122, wherein the heater cover 122 is configured to surround the heater 121 and has a heat transfer surface hs on the outside. The structure of the heater 121 and the heater cover 122 may be the same as the above-mentioned structure.

[0127] like Fig.18 As shown, the heater cover 122 includes a first cover 122a and a second cover 122b, wherein the first cover 122a is arranged on one side of the radial direction b, and the second cover 122b is arranged on the other side of the radial direction b and can be combined with the first cover 122a; wherein the heater 121 can be arranged between the first cover and the second cover. The structure of the first cover 122a and the second cover 122b can be the same as the above structure.

[0128] like Fig.18 As shown, the rotating member 130 may include a rotating pin 131 inserted into the outer cover 140 along the axial direction a.

[0129] At this time, the rotation pin 131 inserted into the outer cover 140 can be configured to rotate relative to the outer cover 140. That is, the rotation pin 131 can rotate relative to the outer cover 140 while being inserted into the outer cover 140, so the outer cover 140 can rotate more smoothly.

[0130] In addition, during the rotation of the outer cover 140, heat can be transferred by conduction through the rotating pin 131, thereby also improving the thermal massage effect.

[0131] At this time, the inner surface of the outer cover 140 may also have a sliding surface. When the massage ball 100 presses the user, even if the outer cover 140 is deformed and contacts the heater cover 122, the outer cover 140 can rotate smoothly as long as it has the sliding surface.

[0132] like Fig.18 As shown, the outer cover 140 has a cover slot 143 into which the rotating member 130 is inserted, and a cover opening 144 may be provided inside the cover slot 143 in the radial direction b to expose a portion of the rotating member 130 in the radial direction b.

[0133] That is, the rotating member 130 is exposed inside the cover slot 143 in the radial direction b through the cover opening portion 144 , and the portion exposed inside the radial direction b receives heat transfer in a conductive manner while contacting the heater cover 122 .

[0134] like Fig.18 As shown, the rotating member 130 may have an exposed contact portion 131 a , and the exposed contact portion 131 a is exposed inside in the radial direction b through the cover opening 144 .

[0135] That is, the exposed contact portion 131 a exposed to the outside in the radial direction b contacts the external cover 140 while transferring heat in a conductive manner.

[0137] Fig.21 As Fig.19 A cross-sectional view of the Ⅰ-Ⅰ portion is a diagram showing a second modified example of the cover slot; Fig. 22 As Fig.19 The cross-sectional view of the Ⅰ-Ⅰ portion is a diagram showing a third modified example of the cover slot.

[0138] like Figures 19 to 22As shown, the cover slot 143 may include at least one of a first cover slot 143a and a second cover slot 143b, wherein the first cover slot 143a extends from one side of the axial direction a to the other side, and the second cover slot 143b extends from the other side of the axial direction a to one side.

[0139] For example, Fig. 20 As shown, the cover slot 143 may include a first cover slot 143a extending from one side of the axial direction a to the other side. In this case, an anti-detachment surface may be provided on the other side of the axial direction a of the first cover slot 143a to prevent the rotation pin 131 from detaching. With such a configuration, a worker can perform simple assembly by inserting the rotation pin 131 from one side of the axial direction a to the other side, thereby improving the assembly performance.

[0140] Take another example, Fig.21 As shown, the cover slot 143 may include a second cover slot 143b, and the second cover slot 143b extends from the other side of the axial direction a to one side. In this case, an anti-detachment surface may be provided on one side of the axial direction a of the second cover slot 143b to prevent the rotation pin 131 from detaching. With such a configuration, the staff can perform simple assembly by inserting the rotation pin 131 from the other side of the axial direction a to one side, thereby improving the assembly performance.

[0141] At this time, the cover slot 143 includes a first cover slot 143a and a second cover slot 143b, wherein the first cover slot 143a extends from one side to the other side of the axial direction a, and the second cover slot 143b extends from the other side to one side of the axial direction a, and the first cover slot 143a and the second cover slot 143b are alternately arranged along the circumferential direction c or can be arranged along the axial direction a.

[0142] For example, the cover slot 143 includes a first cover slot 143a and a second cover slot 143b, wherein the first cover slot 143a extends from one side of the axial direction a to the other side, and the second cover slot 143b extends from the other side of the axial direction a to one side, and the first cover slot 143a and the second cover slot 143b can be alternately arranged along the circumferential direction c. If so configured, one side of the axial direction a of the external cover 140 is supported by the rotation pin 131 inserted in the first cover slot 143a, and the other side of the axial direction a of the external cover 140 is supported by the rotation pin 131 inserted in the second cover slot 143b, so that the external cover 140 can rotate smoothly.

[0143] Take another example, Fig. 22As shown, the cover slot 143 includes a first cover slot 143a and a second cover slot 143b, wherein the first cover slot 143a extends from one side of the axial direction a to the other side, and the second cover slot 143b extends from the other side of the axial direction a to one side, and the first cover slot 143a and the second cover slot 143b can be arranged along the axial direction a.
